Jesus, through the Course, tells us: "What you see reflects what you think, and what you think is nothing but a reflection of what you want to see." Simple, concise.
What are you thinking about?
What do you want to see?
Two excellent questions for you to put into practice.
And he uses a word that no one notices: "reflects." What does he mean by "reflects"? Or, is it a reflection of what?
He's talking about your subconscious. That's where the programs, the wrong decisions, that make your life what it is are. Situations from your childhood, adolescence, or even adulthood. The remedy is Atonement; there is no other. From this, it follows that many disciplines cannot transform your life, or change you, or make you stop being who you are and become who you truly are.
Is Atonement Jesus? He often needs an instrument, a teacher of God on earth, to help you Atone. Simple and concise.
